A few weeks ago I posted about a seized bottom bracket. Well I got around to it finally, I got it off. I applied heat some spray. A large crescent wrench kept sliding off so we put a C clamp on the wrench to hold it on. With some force it came off. Thanks a got the bike rolling again.
Good job! I've found a pipe-wrench works well in difficult cases too. I always use some teflon plumbing-tape on the cups when re-installing. Prevents seizing due to corrosion over time, and it fills the gaps in the threads so no creaking allowed!
